The fire extinguisher must be weighed after being filled with dry powder to ensure that the amount of dry powder filled is within a predetermined range. The traditional weighing method is to take the fire extinguisher off the conveyor belt for weighing, which not only needs more manpower and increases the labor intensity of the manpower, but also can miss the weighing of the fire extinguisher due to the negligence of the man-made person, thus leading the defective products to flow into the market.
Disclosure of Invention
The utility model aims at providing a fire extinguisher weight on-line measuring device can carry out weight detection to the fire extinguisher on the conveyer belt, when reducing artifical intensity of labour, guarantees the reliability that fire extinguisher weight detected.
The utility model discloses an on-line detection device for the weight of a fire extinguisher, which comprises a weighing mechanism, and is characterized in that the weighing mechanism consists of a weight sensor, a lifting mechanism, a push plate and a driving mechanism, wherein the lifting mechanism and the driving mechanism are respectively arranged on a bracket, and the bracket is erected on the weight sensor; the driving mechanism is connected with the push plate to drive the push plate to move in a reciprocating mode, and the push plate and the lifting mechanism are opposite and are located on two sides of the fire extinguisher conveying belt respectively.
The weighing principle of the weighing mechanism is as follows:
when the filled fire extinguisher moves to the push plate along with the conveyer belt, the driving mechanism drives the push plate to push out, the fire extinguisher is pushed to the lifting mechanism, after the bottom end of the fire extinguisher contacts the lifting mechanism, can move upwards under the combined action of the lifting mechanism and the push plate to separate the bottom end of the fire extinguisher from contact with the conveyer belt, the fire extinguisher keeps stable under the matching of the push plate and the lifting mechanism, and is in a nearly vertical state, the weight sensor weighs the total weight of the lifting mechanism, the push plate and driving mechanism, the bracket and the fire extinguisher, because the mass of the lifting mechanism, the push plate, the driving mechanism and the bracket is known and remains unchanged, the weight of the lifting mechanism, the push plate, the driving mechanism and the bracket is subtracted from the weighed total weight, the weight of the fire extinguisher can be known, and through practical use, the weighing precision can be accurate to grams, so that the weight detection requirement of the fire extinguisher can be met.
After weighing, actuating mechanism drive push pedal slowly retracts, and after the fire extinguisher lost the support of push pedal, the height was reduced gradually under the effect of lifting mechanism, and it is steady to resume to the bottom of fire extinguisher and conveyer belt again contact, and the conveyer belt is marchd and can be driven the fire extinguisher and break away from gradually with the contact of lifting mechanism for the fire extinguisher can be marchd along with the conveyer belt again. In the bearing process, the conveying belt does not need to stop, and the normal conveying beat cannot be influenced.
Specifically, the lifting mechanism includes the following two types:

The push pedal pushes the fire extinguisher to the inclined plane, so that the bottom end of the fire extinguisher contacts the inclined plane, the fire extinguisher can move upwards to the inclined plane under the pushing of the push pedal, the push pedal continues to push the fire extinguisher at the moment, the bottom end of the fire extinguisher can be separated from the contact with the conveying belt, and the fire extinguisher keeps balance under the combined action of the inclined plane and the push pedal.
2. The lifting mechanism is a vertical cylinder, and a lifting platform is arranged at the end part of a piston rod of the vertical cylinder. At initial state, the piston rod is in the contraction state, and the high parallel and level of lifting platform and conveyer belt or slightly less than the conveyer belt, the push pedal is pushed the fire extinguisher to the lifting platform, makes the bottom of fire extinguisher contact the lifting platform, and the piston rod upwards stretches out this moment, makes the bottom of fire extinguisher break away from the contact with the conveyer belt, and the fire extinguisher keeps balance under the combined action of lifting platform and push pedal.
Furthermore, for making the fire extinguisher stable at the bearing in-process state, inclined plane or lifting platform are equipped with the baffle in the one side of keeping away from the conveyer belt, and the baffle can prevent that the fire extinguisher from empting to the conveyer belt outside during weighing.
Furthermore, the side of the push plate, which is in contact with the fire extinguisher, is provided with a concave part, so that the fire extinguisher can be supported in multiple directions when bearing, and the fire extinguisher is prevented from toppling over.
Further, the weighing mechanism further comprises a controller, a position sensor and a blocking mechanism, the position sensor is used for detecting the position of the fire extinguisher, the blocking mechanism is used for controlling the fire extinguisher to move, the controller is respectively connected with the driving mechanism, the position sensor, the weight sensor and the blocking mechanism, and the blocking mechanism is located in front of the lifting mechanism. When the position sensor detects that the fire extinguisher moves to the position near the push plate, the position sensor sends a control signal to the controller, and the controller controls the push plate to be pushed out through the driving mechanism to carry out weighing measurement; after weighing, the weight sensor sends a control signal to the driving mechanism, and the driving mechanism controls the push plate to retract again, so that the fire extinguisher advances along with the conveying belt again, the automation degree of the weighing mechanism is improved, and the automatic detection of the weight of the fire extinguisher on the conveying belt is realized under the condition of no need of human participation. In the weighing process, the controller stops an unweighted fire extinguisher (namely the next fire extinguisher to be weighed) on the conveying belt by using the blocking mechanism so as to prevent the fire extinguisher from colliding with the fire extinguisher being weighed and influencing the normal weighing work, and after the fire extinguisher is weighed, the next fire extinguisher is released to move to the push plate.
To the defective products that probably appear, the utility model discloses a fire extinguisher weight on-line measuring device has following two kinds of modes of dealing with:
